Hi,

> warning: variable ?md? set but not used [-Wunused-but-set-variab

There is no errors at all in there so :

- Either it was a parallel build and you didn’t paste the right  
section of the output
- The process was just OOM killed by lack of memory (which you can  
check by looking at ‘dmesg’ output)

Cheers,

Sylvain
